ABSTRACT: One of the primary needs for socio-economic development in any nation in the world is the reliable electricity supply system. Renewable energy technologies offers clean, abundant energy gathered from self-renewing resources such as the sun, wind etc. As the power demand increases, power failure also increases. So, renewable energy sources can be used to provide constant loads. Wind energy is expected to be one of the most prominent sources of electrical energy in years to come. In this paper wind energy conversion system is integrated with the grid. Wind turbines are packaged systems that include a rotor, a generator, turbine blades, a drive and coupling blades. This process reveals a unique step in electricity generation and availability from natural resources without hampering the ecological balance. The goal of this paper to build a complete model of integrated wind energy conversion system with grid in MATLAB/Simulink. KEY-WORDS: Socio-economic, Wind energy, MATLAB/ Simulink, integrated generation INTRODUCTION: Recent developments and trends in the electric power consumption indicate an increasing use of renewable energy resources (RES). Maximum energy demand is supplied by the burning of fossil fuels. Hence increasing air pollution, global warming, diminishing fossil fuels and their increasing cost have made it necessary to look towards RES as a future energy solution.[2] Solar energy and wind energy is clean, inexhaustible, unlimited, and environmental friendly. Such characteristics have attracted the energy sector to use renewable energy sources on a larger scale. However, all renewable energy sources have drawbacks. Wind is dependent on unpredictable factors such as weather and climatic conditions. Wind power is another most competitive renewable technology and, in developed countries with good wind resources, onshore wind is often competitive with fossil fuel fired generation. Wind power generation has experienced a tremendous growth in the past decade,
and has been recognized as an environmental friendly and economically competitive means of electric power generation.[5] The wind energy system generates power in the form of AC with different voltage and frequency levels in case of variable speed operation. In this paper wind energy conversion system is simulated using MATLAB. Output of this system is connected to the grid through point of common coupling (PCC). WIND ENERGY SYSTEM: Wind power systems convert the kinetic energy of the wind into other forms of energy such as electricity. Although wind energy conversion is relatively simple in concept, turbine design can be quite complex. Most commercially available wind turbine uses a horizontal – axis configuration with two or three blades, a drive train including a gearbox and a generator and a tower to support the rotor.[6] The power available in the wind is proportional to the cube of its speed. This means that if wind speed doubles, the power available to the wind generator increases by a factor of 8 (2 x 2 x 2 = 8) Since wind speed increases with height increases to the tower height can mean enormous increases in the amount of electricity generated by a wind turbine.
